phas servers don't send email directly, so PHP's mail() function doesn't
work. A site that relies on it fails quietly: contact-form messages,
password resets and order emails never arrive.
Send through an email service instead:
| Option | Good for |
|---|---|
| Transactional Email add-on | Any site. Up to 25,000 emails a month, with bounce tracking. The one to use for Microsoft 365 and Google Workspace domains. |
| Your mailbox provider's SMTP | Low volume, if your provider lets apps sign in to SMTP, for example with an app password. |
Microsoft 365 and Google Workspace don't make SMTP from a website easy, so for domains on those, use Transactional Email.
WordPress
- In WordPress, go to Plugins → Add New, then install and activate WP Mail SMTP. If it's already installed, skip to step 2.
- In WP Mail SMTP → Settings, set From Email to an address on your domain.
- Choose the mailer:
- With Transactional Email: choose Postmark and paste the Server API token from the Transactional Email page in phas. The From address must be on a verified sending domain.
- With another mailbox provider: choose your provider if it's listed, or Other SMTP with the SMTP details your provider gives you.
- Send a test from WP Mail SMTP → Tools → Email Test.
Other apps
Point the app's mail settings at your mailbox provider's SMTP, or at Transactional Email through Postmark's API or one of its libraries. See Set up Transactional Email.
